Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing technology, specifically to a device for bursting the shell of camellia oleifera fruit. Background Technology

[0002] Camellia oleifera fruit is an important woody oil crop, and the shell-breaking process is a crucial step in extracting camellia seeds during post-harvest processing. Currently, common camellia oleifera fruit shell-breaking equipment mainly includes roller pressing, hammering, rubbing board, and centrifugal impact types. Their basic principle is to break the fruit shell through the squeezing, impact, or friction between rigid components, thereby separating the kernel from the outer shell.

[0003] However, existing shell-breaking devices generally have a fixed shell-breaking gap, which generally has poor adaptability and poor discharge of the shell-kernel mixture when faced with a variety of camellia fruits of different sizes. Moreover, existing devices mostly use rigid extrusion, which can easily cause the internal kernels to be crushed or cracked during the shell-breaking process. Severe kernel damage affects the oil extraction efficiency and product grade.

[0004] To address this issue, a device for bursting the shells of camellia fruit is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a camellia fruit bursting device, which solves the problems of poor adaptability, difficulty in compatibility with different sizes of camellia fruits, and poor material discharge smoothness of existing camellia fruit bursting devices.

[0006] This utility model achieves the above objectives through the following technical solutions: A device for bursting the shell of camellia fruit includes: frame; The outer frame is fixedly installed inside the frame and includes multiple outer rods evenly distributed along the circumference; The inner frame is rotatably disposed within the frame and coaxially arranged with the outer frame, and includes multiple inner rods evenly distributed along the circumference. A feeding hopper is located above one end of the outer frame and is used to feed camellia fruit whose shells are to be popped. A drive mechanism, located on one side of the frame, is used to drive the inner frame to rotate so that the outer rod and the inner rod cooperate to squeeze the camellia fruit to achieve the bursting of the shell.

[0007] As a further optimization of this utility model, the inner frame also includes a rotating shaft, and a first end plate and a second end plate fixedly sleeved on the rotating shaft; the first end plate has a plurality of first mounting holes evenly distributed along the circumference, and the second end plate has a plurality of second mounting holes corresponding one-to-one with the first mounting holes, and each inner rod is correspondingly inserted and fixed between the first mounting hole and the corresponding second mounting hole.

[0008] As a further optimization of this utility model, the frame includes two symmetrically distributed side plates, multiple connecting rods for fixing the two side plates together, and a top plate that spans and is fixedly installed on the top of the two side plates; a supporting channel steel is fixedly installed at the bottom of each of the two side plates, the outer rod is fixedly installed between the two side plates, and the rotating shaft is rotatably installed between the two side plates.

[0009] As a further optimization of this utility model, the feed hopper is fixedly mounted on the top plate, and an arc-shaped plate is fixedly mounted at the bottom of the feed hopper, with both ends of the arc-shaped plate fixed between two side plates.

[0010] As a further optimization of this utility model, the driving mechanism includes a motor fixedly mounted on the top of the top plate, a first pulley fixedly sleeved on the output shaft of the motor, a second pulley fixedly sleeved on the rotating shaft, and a belt wound between the first pulley and the second pulley.

[0011] As a further optimization of this utility model, the circumferential diameter of the first mounting hole is larger than that of the second mounting hole, so that the inner rod is arranged inclined along the axial direction; the circumferential diameters of the two ends of the outer rod are the same; and the feed hopper is located above the high end of the inner rod.

[0012] As a further optimization of this utility model, the inner rod extends spirally along its axial direction, with one end connected to the first mounting hole on the first end plate and the other end connected to the second mounting hole on the second end plate at a corresponding position deflected by 45°, so as to form a spiral structure twisted by 45° relative to the axis of rotation.

[0013] As a further optimization of this utility model, a silicone sleeve is provided around the outer periphery of the outer rod.

[0014] The beneficial effects of this utility model are as follows: 1. This utility model drives the inner frame to rotate, so that the outer rod and the inner rod work together to squeeze the camellia fruit to achieve automatic shell bursting. The inner rod adopts an axially inclined and 45° twisted spiral structure design. During the rotation process, it can not only apply radial extrusion force to the camellia fruit to complete the shell cracking, but also generate a stable axial spiral propulsion force, realizing the integrated function of shell breaking and automatic material discharge, effectively avoiding material accumulation or blockage. The spiral inclined channel has good size adaptability and can be compatible with different varieties and particle sizes of camellia fruit, significantly improving the shell bursting adaptability of the device.

[0015] 2. The silicone sleeve of this utility model can give the outer rod body elasticity, which can buffer the rigid impact during the extrusion process. Combined with the stable support of the inner rod body, it can reduce the breakage rate of the kernel while ensuring the completeness of the shell bursting. At the same time, the elasticity can also make the device compatible with camellia fruits of different sizes. Attached Figure Description

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1 To address the issues of poor adaptability, incompatibility with different sizes of camellia fruit, and poor discharge smoothness in existing camellia fruit cracking devices, please refer to... Figures 1-4 The present invention provides a camellia fruit bursting shell device, comprising: Rack 1; The outer frame 2 is fixedly installed inside the frame 1 and includes multiple outer rods 201 evenly distributed along the circumference. The inner frame 3 is rotatably mounted inside the frame 1 and coaxially arranged with the outer frame 2, and includes multiple inner rods 304 evenly distributed along the circumference; Feed hopper 4 is located above one end of the outer frame 2 and is used to feed the camellia fruit whose shells are about to burst. The drive mechanism 5 is located on one side of the frame 1 and is used to drive the inner frame 3 to rotate so that the outer rod 201 and the inner rod 304 cooperate to squeeze the camellia fruit to achieve the bursting of the shell.

[0020] In use, the camellia fruit to be popped is fed into the feed hopper 4. The camellia fruit falls through the gap between the outer rods 201 into the working gap between the inner frame 3 and the outer frame 2. The drive mechanism 5 drives the inner frame 3 to rotate. The inner rod 304 and the outer rod 201 of the outer frame 2 form a dynamically changing compression space. The camellia fruit is subjected to continuous compression and friction in the gap, and the shell gradually cracks, thus popping the shell. The popped camellia fruit kernel and shell are discharged from the gap between the adjacent outer rods 201 at the bottom of the outer frame 2 under the action of gravity.

[0021] The inner frame 3 also includes a rotating shaft 301, and a first end plate 302 and a second end plate 303 fixedly sleeved on the rotating shaft 301; the first end plate 302 has a plurality of first mounting holes 305 evenly distributed in the circumferential direction, and the second end plate 303 has a plurality of second mounting holes 306 corresponding to the first mounting holes 305; each inner rod 304 passes through and is fixed between the first mounting hole 305 and the corresponding second mounting hole 306.

[0022] The frame 1 includes two symmetrically distributed side plates 101, multiple connecting rods 102 for fixing the two side plates 101 together, and a top plate 104 that spans and is fixedly installed on the top of the two side plates 101; a supporting channel steel 103 is fixedly installed at the bottom of each of the two side plates 101, an outer rod body 201 is fixedly installed between the two side plates 101, and a rotating shaft 301 is rotatably installed between the two side plates 101.

[0023] The feed hopper 4 is fixedly mounted on the top plate 104. An arc plate 401 is fixedly mounted at the bottom of the feed hopper 4, and the two ends of the arc plate 401 are fixedly mounted between the two side plates 101.

[0024] The drive mechanism 5 includes a motor 501 fixedly mounted on the top of the top plate 104, a first pulley 502 fixedly sleeved on the output shaft of the motor 501, a second pulley 503 fixedly sleeved on the rotating shaft 301, and a belt 504 wound between the first pulley 502 and the second pulley 503. When the drive mechanism 5 is in use, the motor 501 drives the first pulley 502 to rotate, and through the transmission action of the belt 504, it synchronously drives the second pulley 503 to rotate. The second pulley 503 drives the rotating shaft 301 to rotate, thereby driving the entire inner frame 3 to rotate around its own axis.

[0025] To enhance the adaptability of the device for cracking the shells and to ensure the continuous and orderly discharge of camellia oleifera fruits after cracking, such as... Figure 4 As shown, the circumferential diameter of the first mounting hole 305 is larger than that of the second mounting hole 306, so that the inner rod 304 is arranged at an angle along the axial direction, forming a spatial layout with one end high and the other end low; the feed hopper 4 is located above the high end of the inner rod 304.

[0026] The inner rod 304 extends spirally along its axial direction, with one end connected to the first mounting hole 305 on the first end plate 302 and the other end connected to the second mounting hole 306 on the second end plate 303, which is deflected by 45° at the corresponding position, so as to form a spiral structure twisted by 45° relative to the axis of the rotating shaft 301.

[0027] During operation, the camellia fruit to be popped is fed into the high end of the inner rod 304 through the feed hopper 4 and falls into the working gap between the inner frame 3 and the outer frame 2. The drive mechanism 5 drives the inner frame 3 to rotate. Since the inner rod 304 has both axial inclination and a 45° twisting spiral feature, it applies axial thrust to the mixture of kernel and shell after popping during the rotation process, so that the material is gradually pushed from the high end to the low end along the inclined direction, and finally discharged continuously and orderly from the low end of the device. This greatly improves the adaptability of the device to popping, and it can be compatible with different varieties and sizes of camellia fruit, avoiding small fruit leakage and large fruit jamming.

[0028] Furthermore, the two ends of the outer rod 201 have the same circumferential diameter, ensuring that they are arranged in a horizontal ring. This forms an asymmetrical dynamic extrusion gap with the inclined and spirally arranged inner rod 304, which helps to improve the shell breaking efficiency and prevent material jamming. The center distance between the first mounting hole 305 and the rotating shaft 301 is 112.5 mm, the center distance between the second mounting hole 306 and the rotating shaft 301 is 80 mm, the center distance between the outer rod 201 and the rotating shaft 301 is 150 mm, the diameter of the outer rod 201 is 12 mm, and the diameter of the inner rod 304 is 18 mm. This size configuration ensures sufficient extrusion strength while optimizing material throughput and movement trajectory, ensuring the coordination and stability of the shell breaking and discharge process.

[0029] Example 2 Based on Example 1, in order to reduce mechanical damage to the camellia kernels while effectively breaking the shell, such as... Figure 5 As shown, a silicone sleeve 202 is fitted around the outer periphery of the outer rod body 201.

[0030] The silicone sleeve 202 is made of elastic polymer material, which has good flexibility and resilience. When the camellia fruit passes through the extrusion area between the inner frame 3 and the outer frame 2, the silicone sleeve 202 can undergo local deformation under the action of external force to form a buffer contact interface, thereby reducing the breakage or crushing of the kernel caused by rigid collision. At the same time, its high coefficient of friction helps to enhance the gripping force on the shell, prevent slippage, ensure that the camellia fruit is stably stressed during the rotation and extrusion process, improve the uniformity and integrity of shell breaking, and reduce operating noise.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
